Hydraulic system
Note:
The EC "Machinery" Directive 89/392/EEC stipulates
that all formwork systems that are moved either
electrically or hydraulically are subject to manda-
tory CE labelling requirements. For this reason, a
hazard analysis and an Operating Instructions man-
ual must be drawn up for the entire system, in every
case.
The formwork is moved by means of a hydraulic
branch-line system.
● The hydraulic unit has 6 hydraulic outlets.
These assure the same constant delivery rates,
regardless of the load pressure.
● In practice, 6 cylinders are often not sufficient.
It is possible to increase the number of cylinders
by using the Hydraulic distributor, art.n°
580808000 (I) . This divides up the 6 hydraulic cir-
cuits A-F into 3 groups of 6 hydraulic circuits
(makes it possible to connect up to 18 cylinders)
Due to the many different strokes and load ratings
for hydraulic cylinders used in the formwork tech-
nology field, it is difficult or impossible to standard-
ise cylinders. This is why in most cases, custom cyl-
inders are used.
Planning note
Important where the cylinder is subjected to
push/pull loads:
Hydraulic unit
Note:
If the unit needs to be lifted, it should only be slung
from, and lifted by, the crane hoisting lugs pro-
vided.
Hydraulic unit for forming-operations
Is supplied to the site ready for operation.
☞
When the distribution valves are being
switched over, the switch passes through an
intermediate position which may cause
unintentional lowering of the load.
Remedy: Fit lowering brake-valves to the
load-side of the hydraulic cylinders.
